  • The Problem with Humidity in SF6 Gas-Insulated Systems

    To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

    Description. 973-SF6 gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and

  • Measuring Dew Point and Moisture in SF6 Gas

    Sulfur hexafluoride (SF6) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).
